How to relieve muscle tendon stiffness in knees.

The back of the knee is called the "popliteal" region of the knee.
The depression in the middle of the back of the knee is called the "popliteal fossa".

Doctors refer to pain at the back of the knee as "popliteal pain".
Popliteal pain may arise from a number of causes Doctors refer to pain at the back of the knee as "popliteal pain".
Popliteal pain may arise from a number of causes

Common causes of pain at the back of the knee

Baker's cyst

One of the common causes of popliteal pain is a Baker's cyst (or popliteal cyst). This is a fluid-filled lump at the back of the knee caused by fluid which has built up under pressure within the knee cavity in response to an inflammatory problem within the knee and not directly related to the lump itself.

The space within the knee joint is lined by cells that secrete lubricating fluid (synovial fluid). If the knee is stressed for any reason excessive fluid can be secreted. In the popliteal region of the knee there is an anatomical connection between the main joint cavity and a lubricating 'pocket' at the back of the knee (the gastrocnemio-semimembranous bursa). When the fluid builds up under pressure, synovial fluid can leak into the popliteal bursa to form a cystic swelling known as a Baker's cyst (or popliteal cyst). The cyst may be obvious to the eye or it may be palpable as a tense 'balloon-like' swelling on the inner (medial) aspect of the back of the knee.

 

Popliteus tendinitis

Another condition that can cause popliteal pain is 'popliteus tendinitis'. This is an inflammation of the tendon of the popliteal muscle. The popliteus tendon is very unusual. If you look at the second illustration, where the knee capsule has been sketched in, you can see that the popliteus tendon actually passes through the capsule of the knee and into the knee joint itself, where it attaches to the outer side of the femur.In doing so, it runs behind the lateral meniscus and in close proximity to it.

The popliteus tendon is sensitive to overuse activity and may become inflamed (tendinitis) causing pain at the back of the knee, aggravated during deep squats. The patient may also have trouble fully straightening the knee. Popliteus tendinitis pain can often be elicited by bending the knee and resting the ankle onto the shin of the other leg in a figure-of-4 position. Sitting on a table with the lower legs dangling, pain may also be elicited when an examiner rotates the foot and tibia outwards.

 

Injury to the posterior horn of the meniscus

Another cause of popliteal pain is a disruption at the back of the lateral meniscus, in the region known as the 'posterior horn'. The illustration on the left shows a bird's-eye view of the menisci sitting on the top of the tibia. You can see that the lateral meniscus is a different shape from the medial meniscus in being more 'O'-shaped rather than 'C'-shaped, and in having a recess at the point where the popliteal tendon passes up to the femur bone. The presence of the popliteus means that the lateral meniscus is not tethered at its outer rim as well as the medial meniscus, and it is consequently more mobile.

If we consider just the bit at the back of the knee - the posterior horn - of the lateral meniscus, there may be a tear of the meniscus itself, or there may be a disruption in the fibres that frequently attach the rim of the posterior horn to the popliteus tendon as it sweeps along the back of the meniscus. Either of these possibilities may result in pain at the back of the knee. The pain may be accompanied by feelings of knee instability and giving way.

Hamstrings tendinitis (biceps femoris tendinitis)

Inflammation of the biceps femoris tendon as it sweeps along the back of the knee may give rise to pain in this area. The biceps femoris tendon is one of the hamstrings tendons. It may become damaged via overuse during a repetitive activity such as running or cycling, where the tendon abrades over the bone of the femur at the back of the knee. The pain is experienced at the outer side of the knee at the back.

 

 

Gastrocnemius tendinitis

The other tendon inflammation that may cause pain at the back of the knee is gastrocnemius tendinitis. Pain may be experienced on the inner or outer aspects of the back of the knee.

Yakasaisen A brand (herbal medication)

Indications: for wasting disease (such as stiffness of knee, tendons, ligaments,
waist pain, knee stiffness no pain, knee pain, back pain (musculotendinous strain),

but it can relieve that symptom and also stiffness of tendons, ligaments, waist pain, knee pain and back pain.

For patients who have herniated disk we recommend chiropractic treatment together with Ya kasaisen A brand.

In case of Herniated Nucleus Pulposus, most patients will get better and experience no pain after getting massages,
and getting muscle relaxant & anti-inflammation medication,
but pain symptoms will come back after the medication effects wear off.
The symptoms of Herniated Nucleus Pulposus are as follows:

Having intermittently pain or stiffness, or changing positions of pain, getting better after have massages,
but pain symptoms coming back after for a period.

Ya Kasaisen A brand can treat stiffness of tendons, ligaments symptoms, and pain of a wasting disease.

Ya Kasaisen A brand uses an original recipe from traditional treatment Doctor Ruangyot’ father.
He had knowledge of Chinese herbal medicine, and he discovered this Ya Kasaisen A brand recipe
in order to treat tendon stiffness in himself;
the symptoms improved a lot step by step until he recovered completely.
Therefore, he would like to help other patients, so he registered this Ya Kasaisen.

What is a wasting disease or Kasaisen

"Ya" in the word of Thai meaning "medicine".

The word of wasting disease or “Kasaisen” in terms of Thai traditional medicine means
a disease caused by degradation of the physical body;
the word "sen" in this context means tendons, ligaments, and all the muscles of the body.

Symptoms of wasting disease or “Kasaisen” are as follows:
1.Inflammation of tendons, pain (or burning pain) in tendons or arms or legs.
2.Back pain (back tendon or back muscle pain) or lumbar pain down to the legs,
some cases pain all the way down to the feet.
3.Stiffness or tension or cramps in arms, legs, abdomen, and behind the neck.
This can cause of inability to lift arms, difficulty with squatting or sitting on the floor,
difficulty with standing up or twisting the body.
4.Body pain, such as pain in shoulders, arms or legs, inability to stretch arms up.
5.Plantar fasciitis, sore feet or heels make walking difficult.
6.Knee pain or swelling (patients who have been diagnosed with osteoarthritis
mostly have knee stiffness, while other patients have a spiral lump or varicose vein behind the knee).
7.Knee stiffness no pain.
8.Stiff tendons behind knee.
9.Stiffness of tendons, ligaments; some patients get well after getting massage,
but pain comes back again after 1-2 days.
